Below is a video of Peterborough's John Grant Jr. (take a look at his trick shots, too) making the Legendary Mammoth Burger, which will be available for a limited time at the Hard Rock Cafe in Denver. The burger includes 24 ingredients (Grant's number in lacrosse). He will also be taking on all challengers in a speed eating contest. Grant, of course, stars for the Peterborough Lakers in the MSL and plays pro with the Colorado Mammoth in the National Lacrosse League.
